Because Text::Clevery is implemented using Text::Xslate and because Text::Xslate and Text::Xslate::PP trample over each other if they're used in the same program there's no way to safely provide a TextCleveryPP plugin,
however if you set the XSLATE environment variable to pp as documented in Text::Xslate::PP,
this plugin will detect that you're using the pure-perl backend.
